| Summary: | Microfluidic is a science and system technology that processes and manipulates a
small amount of fluid in a channel with tens to hundreds of micrometers. This
technology has the unique features and characteristics of fluid because of the
manipulation that can be performed. Thus, microfluidic has many benefits in their
application in both biology and chemistry research fields. Regardless of its benefits
and advantages, this technology has constraints in terms of its fabrication. The
standard fabrication method of microfluidics tent to have a high cost, timeconsuming, and still have the risk of failure from the final fabrication result. In this
research, a microfluidic device will be fabricated as an observation chamber and
sensor integration. This research will focus on the fabrication of microfluidic
devices using a more time and cost-efficient method, the 3D printing method. The
effect of the 3D-print parameters on resolution and accuracy will be determined.
Besides, the performance and characteristics of the microfluidic devices will also
be determined.
Through this experiment, the 3D printed fabrication method able to form a fluidics
platform up to sub-mm (0,5 – 1 mm) regimes and large microfluidics (100 – 500
µm). The smallest dimension of the observation chamber fabricated in this
experiment is 0,55 mm with exposure time 6 s and vertical print orientation. For
flow-cell, the smallest dimension that successfully fabricated is 0,3 mm with
exposure time 6s and horizontal print orientation. Based on this experiment, the
hydrophilic surface characteristic was found on 3D printed fluidic platforms with
an average contact angle is 62,43º. Flow test showed that both observation
chamber and flow-cell have good coverage and no leakage. This test also indicated
that laminar flow occurred on both fluidic platforms for water with a velocity of
0.189 x 10-3 m/s and a Reynolds number of 0,105. |
